四、爱特1813(2213)CD机这是一台国产CD机中设计、工艺、用料不俗的机子,在音响发烧友中有“中国的CEC891R”的美称。该机音频数模转换电路性能较好,还采用了NE5532作低通滤渡器。故改装时选用了不带音频DAC电路的VCD板。该机的CD—DSP型号为CXD1167Q,晶振频率为16MHz,DSP IC第(50)、(57)脚已接+5V,不用修改数字滤波器模式。但电源变压器功率太小,需另增一只专供VCD板用。
Fourth, Aite 1813 (2213) CD This is a CD player in the design, technology, materials decent decent, audiophiles in the “China’s CEC891R” reputation. The aircraft audio digital-analog conversion circuit performance is better, but also used the NE5532 for low-pass filter. Therefore, when the conversion used without the audio DAC circuit VCD board. The aircraft’s CD-DSP model CXD1167Q, crystal frequency of 16MHz, DSP IC (50), (57) feet have been connected +5 V, without modifying the digital filter mode. However, the power transformer power is too small, need another one for VCD board only.
